Definitions

  • This invention relates to a method of reducing the astringency of an oral care composition, to reduced astringency oral care compositions, and to the use of certain compounds to reduce astringency in oral care compositions.
  • PVM polyvalent metal
  • Astringency in respect to oral compositions, is defined as a complex group of sensations experienced when a substance causes the oral surfaces to feel rough, the mouth to feel dry, and the mucosal surfaces to tighten, draw or pucker.
  • US Patent Application Publication No. 2008/0138298 discloses oral care compositions comprising 0.01-10% of polyphosphorylated inositol derivatives such as phytic acid. These compositions are said to be effective in preventing/controlling disease states whilst having improved aesthetics such as astringency.
  • PVM ion salt astringency has been addressed using monomenthyl succinate salts (WO 98/11867) and poloxamer polymers (WO 00/32160).
  • a method of reducing the astringency of an oral care composition containing PVM ion salts comprising the addition to an oral care composition of at least one of maltol (3-hydroxy-2-methyl-4H-pyran-4-one), ethyl maltol (2-ethyl-3-hydroxy-4H-pyran-4-one), and cyclotene (2-hydroxy-3-methyl-2-cyclopenten-1-one); such that the concentrations of maltol, ethyl maltol, and cyclotene in said oral care composition meet the criterion (M/50+E/50+C/250) ⁇ 1, particularly 1.0-1.5, more particularly 1.2-1.5; wherein M, E and C represent the concentration (in ppm by weight of the total oral care composition) of maltol, ethyl maltol, and cyclotene respectively.
  • oral care composition refers to non-food compositions that are designed to be taken into the mouth to deliver a variety of benefits. Such compositions include dentifrices, mouthwashes, mouth sprays and gargle compositions, breath strips (edible films placed in the oral cavity to administer thereto an active agent such as a flavourant or breath-freshening agent), and chewing gums.
  • dentifrice means toothpaste, oral care gels or liquids, unless otherwise specified.
  • the dentifrice composition may be a single-phase composition or it may be a combination of two or more separate dentifrice compositions.
  • the dentifrice composition may be in any desired form, such as deep striped, surface striped, multilayered, having the gel surrounding the paste, or any combination thereof.
  • an oral care composition comprising at least one PVM ion salt, in particular a zinc salt, and an astringency-counteracting amount of at least one of maltol, ethyl maltol, and cyclotene, such that the concentrations in the said oral care composition of maltol, ethyl maltol, and cyclotene meet the criterion (M/50+E/50+C/250) ⁇ 1, particularly 1.0-1.5, more particularly 1.2-1.5; wherein M, E and C represent the concentration (in ppm by weight of the total oral care composition) of maltol, ethyl maltol, and cyclotene respectively.
  • compositions comprising at least one of maltol, ethyl maltol, and cyclotene, for use in the reduction of the astringency of an oral care composition comprising a PVM ion salt, the concentrations of maltol, ethyl maltol, and cyclotene in the oral care composition being such that they meet the criterion (M/50+E/50+C/250) ⁇ 1, wherein M, E and C represent the concentration (in ppm by weight of the total oral care composition) of maltol, ethyl maltol, and cyclotene respectively.
  • Maltol, ethyl maltol, and cyclotene may be used alone or in combination as the sole components in a composition. Alternatively they may be employed in conjunction with one or more other ingredients commonly used in the art.
  • a method of forming an oral care composition comprising the addition to an oral care composition of at least one of maltol (3-hydroxy-2-methyl-4H-pyran-4-one), ethyl maltol (2-ethyl-3-hydroxy-4H-pyran-4-one), and cyclotene (2-hydroxy-3-methyl-2-cyclopenten-1-one); such that the concentrations in the oral care composition of maltol, ethyl maltol, and cyclotene meet the criterion (M/50+E/50+C/250) ⁇ 1, particularly 1.0-1.5, more particularly 1.2-1.5; wherein M, E and C represent the concentration (in ppm by weight of the total oral care composition) of maltol, ethyl 15 maltol, and cyclotene respectively.
  • Maltol, ethyl maltol, and cyclotene , or compositions containing one or more said compounds can be added to oral care compositions by using conventional techniques to directly admix the said compounds, or composition into the oral care composition.
  • the concentrations of maltol, ethyl maltol, and cyclotene that may be employed in the abovementioned oral care compositions will depend on the concentration of PVM ion salts in the oral care composition. It will also depend on the particular sensorial effect that the formulator is trying to achieve, as these materials are flavoured and, depending on the nature of other flavour ingredients present, may influence the overall hedonic or sensorial effect of the oral care composition.
  • maltol may be employed at levels of at least 50 ppm, more particularly 100 ppm, still more particularly 250 ppm.
  • ethyl maltol may be employed at levels of at least 50 ppm, more particularly 100 ppm, still more particularly 250 ppm.
  • cyclotene may be employed at levels of at least 250 ppm, more particularly 500 ppm, still more particularly 750 ppm.
  • cyclotene is combined with one or both of maltol and ethyl maltol at levels mentioned hereinabove.
  • cyclotene is combined with one or both of maltol and ethyl maltol in a ratio of 1:10 to 10:1, more particularly 1:5 to 5:1.
  • PVM ion salts employed in oral care products can cause astringency.
  • Typical PVM ion salts used in oral care compositions of the present invention are zinc salts, particularly zinc chloride, zinc citrate, zinc acetate, and zinc sulphate, more particularly zinc citrate.
  • the proportion of PVM ion salts usually employed is 0.1 to 2% by weight of the total oral care composition.
  • the reduced astringency oral care compositions of the present invention may also comprise one or more additional ingredients or excipients conventionally used in conjunction with oral 20 care compositions for example, additional flavour compounds and other auxilliary agents commonly used in the art.
  • Differing flavour ingredients were added, at a concentration of 1000 ppm, to a non-flavoured toothpaste base containing 0.75% zinc citrate (ZCT).
  • ZCT zinc citrate
  • Table 1 lists the flavour ingredients added to the non-flavoured toothpaste base containing 0.75% zinc citrate, along with the mean astringency rating of each sample. Also included in table 1 is the mean astringency rating of the non-flavoured toothpaste base containing 0.75% ZCT and the current market product.
  • the toothpaste compositions comprising the flavour materials of the invention, maltol ethyl maltol and cycoltene, all showed significantly lower astringency ratings compared to those of the standard toothpaste base and the current market product.
  • Example compositions containing 2% Zinc Citrate with varying amounts of maltol, ethyl maltol and cyclotene are shown in Table 2.
